DETAILED DESCRIPTION

Embodiments of the present disclosure are described herein. It is to be understood, however, that the disclosed embodiments are merely examples and other embodiments may take various and alternative forms. The figures are not necessarily to scale; some features could be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the embodiments. As those of ordinary skill in the art will understand, various features illustrated and described with reference to any one of the figures may be combined with features illustrated in one or more other figures to produce embodiments that are not explicitly illustrated or described. The combinations of features illustrated provide representative embodiments for typical applications. Various combinations and modifications of the features consistent with the teachings of this disclosure, however, could be desired for particular applications or implementations.

Referring to FIG. 1, a water drainage system 10 is illustrated. The water drainage system 10 may specifically be designed to direct fluid or water away from a house or building in order to prevent runoff water from the house or building from flooding the lower level (e.g., the basement) of the house or building. It should be understood, however, that the water drainage system 10 may be utilized in other scenarios and should not be construed as limited to a water drainage system that is configured to direct water away from a house or building.

As illustrated in FIG. 1, the water drainage system 10 includes tubes, pipes, or conduits 12 that are configured to direct water away from a house or building 14. More specifically, the conduits 12 may be configured to direct water away from a gutter or eavestrough 16 that is disposed along edges of a roof of the building 14. The eavestrough 16 is configured to collect runoff water that cascades down the roof of the building 14 during rainstorms, from melting snow, or from any other source. The conduits 12 are configured to direct the water away from the eavestrough 16 and away from the building 14. More specifically, the conduits 12 may be configured to direct the water toward a storm drain.

Catch basins of storm drains (i.e., the portions of storm drains that are the inlets to a storm drain system that are typically vertically oriented) are usually disposed along an edge of the pavement of a road or street and adjacent to a curb of the road or street. The pavement typically has a slight slope to direct the runoff water from the road or street into the catch basin. The curb may also be positioned above the catch basin and is sloped downward to direct runoff water from the ground that is adjacent to the catch basin toward the catch basin.

The tubes, pipes, or conduits 12 of the water drainage system 10 may include a downspout 18 that is configured to direct water downward from the eavestrough 16 to a drainage tube, pipe, or conduit 20. Stated in other terms, the downspout 18 establishes fluid communication between the eavestrough 16 and the drainage conduit 20. The drainage conduit 20 in turn may be configured to direct water from the downspout 18 to an outlet end 22 of the water drainage system 10. The drainage conduit 20 may include a slight downward slope extending in a direction from the downspout 18 to the outlet end 22 of the water drainage system 10 such that water flows from the downspout 18 to the outlet end 22 of the water drainage system 10. The drainage conduit 20 may include a bend that connects the drainage conduit 20 to the downspout 18. Alternatively, an elbow tube, pipe, or conduit 24 may connect the drainage conduit 20 to the downspout 18. The drainage conduit 20 and the first elbow conduit 24 may collectively be referred to as the drainage tube, pipe, or conduit.

The water drainage system 10 may include a filter 26 that is disposed between the downspout 18 and the drainage conduit 20. The filter 26 may be in fluid communication with both the downspout 18 and the drainage conduit 20. The filter 26 may also establish fluid communication between the downspout 18 and the drainage conduit 20. The filter 26 is configured to filter debris from fluid or water flowing from the downspout 18 to the drainage conduit 20. The filter 26 may be oriented vertically along or adjacent to the downspout 18, which may also be oriented vertically. In some scenarios, the filter 26 may divide the downspout 18 into an upper and a lower conduit. The filter 26 may be referred to as a downspout drain filter.

The drainage conduit 20 and the first elbow conduit 24 may be fully or partially disposed or buried underground, which may be for aesthetic purposes or may be to prevent placing an obstacle on an area of ground that may require maintenance (e.g., the area of ground may include grass that needs to be mowed on a regular basis) or that may have a significant amount of foot traffic. Alternatively, the drainage conduit 20 and the first elbow conduit 24 may be disposed above ground. The outlet end 22 of the water drainage system 10 may be connected directly to a storm drain or more specifically to a catch basin of a storm drain. Alternately, the outlet end 22 of the water drainage system 10 may include an opening that allows water to flow out of the water drainage system 10. Such an opening in the outlet end 22 may be positioned near an opening to a catch basin such that the water flowing out of the opening at the outlet end 22 is directed toward the opening to the catch basin.

As previously stated, the conduits 12 may be configured to direct water away from any source, and this disclosure should not be construed as limited to the layout of conduits 12 in FIG. 1. For example, the elbow conduit 24 is illustrated as a 90° elbow (i.e., an elbow pipe that is bent at about a 90° angle), but may be reconfigured as an elbow that is bent at any desirable angle (e.g., 60°, 45°, and 22.5°, etc.).

Referring to FIGS. 2-3, the filter 26 is illustrated is further detail. The filter 26 includes a housing 28. The housing defines an internal cavity 30, a first opening 32 to the internal cavity 30, a second opening 34 to the internal cavity 30, and a third opening 36 to the internal cavity 30. The first opening 32 to the internal cavity 30 is defined along a top or a top end 38 of the housing 28. The second opening 34 to the internal cavity 30 is defined along a bottom or a bottom end 40 of the housing 28. The third opening 36 to the internal cavity 30 is defined along front face 42 of the housing 28. The first opening 32 is an inlet to the internal cavity 30. The first opening 32 establishes fluid communication between the downspout 18 and the internal cavity 30. The second opening 34 is an outlet from the internal cavity 30. The second opening 34 establishes fluid communication between the internal cavity 30 and the drainage conduit 20.

A filter media or filter plate 44 is disposed within the internal cavity 30. The filter plate 44 may more specifically be a grated plate. The filter plate 44 may be disposed within the internal cavity 30 at an angle relative to a vertical direction 46. The filter plate 44 may divide the internal cavity 30 into an upper chamber 48 and a lower chamber 50. The filter plate 44 is configured to configured to trap debris, such as leaves, in the upper chamber 48 from fluid or water flowing downward through the internal cavity 30, while also being permeable such that the fluid or water flows through the filter plate 44 from the upper chamber 48 to the lower chamber 50.

A door or access panel 52 is secured to the housing 28 and over the third opening 36. The access panel 52 is configured to provide access to the upper chamber 48 for removal of debris trapped within the upper chamber 48. The housing 28 may further define an overflow opening 54 that is disposed above the access panel 52 along the top end 38 of the housing 28. The overflow opening 54 may be grated to prevent debris from entering into the internal cavity 30 via the overflow opening 54. If grated, the overflow opening 54 may more specifically comprise an array or a series of adjacent openings. The overflow opening 54 is configured to direct the fluid or water out of the internal cavity 30 in response to the filter plate 44 becoming clogged and fluid or water filling the upper chamber 48. The overflow opening 54 may be in direct fluid communication with the upper chamber 48.

The overflow opening 54 may be defined along the top of the upper chamber 48 so that under most conditions fluid or water will not flow out of the overflow opening but will flow downward via gravity through the filter plate 44 and out of the internal chamber 30 via the outlet or second opening 34. Only when the rate of fluid or water flowing into the upper chamber 48 via the inlet or first opening 32 exceeds the rate of fluid or water flowing through the filter plate 44 for a period of time, will the fluid or water flow out of the overflow opening 54. The fluid or water flowing out of the overflow opening 54 may then function as a signal that debris, such as leaves, has clogged the filter plate 44. Such a signal may act to notify an individual that is responsible for maintaining the filter 26 that debris needs to be removed from the internal cavity 30, or more specifically that debris needs to be removed from the upper chamber 48 of the internal cavity 30.

The overflow opening 54 may be positioned adjacent to and above the front face 42. The front face 42 and overflow opening 54 may be positioned to face outward from a building or house that the downspout 18 and filter 26 are secure to, so that is it easy to observe fluid or water flowing out of the overflow opening 54. The overflow opening 54 may also be orientated at an angle relative to the front face 42 of the housing 28, such that fluid or water flowing out the overflow opening 54 may be directed partially upward and partially outward from the filter 26. This further increases the ease of observing fluid or water flowing out of the overflow opening 54, since the fluid or water is being directed outward from the filter 26 and not simply downward where the fluid or water may trace along the outer surface of the filter 26 or any adjacent conduit that is disposed below the filter 26, which would be more difficult to observe particularly from a distance.

Referring now to FIGS. 2-5, the top end 38 and the bottom end 40 of the housing 28 are described in further detail. The top end 38 of the housing 28 may be a separate component from a remainder 56 of the housing 28. The top end 38 of the housing 28 may be secured to the remainder 56 of the housing 28 via fasteners, clips, snaps, etc. The top end 38 of the housing 28 and the remainder 56 of the housing 28 may also defines slots 58, that are configured to receive portions of the filter plate 44 and the access panel 52. The sections of the top end 38 of the housing 28 and the remainder 56 of the housing 28 that are adjacent to the slot 58 may function to trap the portions of the filter plate 44 and the access panel 52 within the slots 58 to retain the filter plate 44 and the access panel 52 in desired positions (e.g., the positions depicted in FIGS. 2-3). The filter plate 44 and the access panel 52 may be flexible so that the filter plate 44 and the access panel 52 may be manipulated into and out of the respective desired positions during installation onto or removal from the housing 28. The filter plate 44 and the access panel 52 may also be sufficiently rigid to remain in the respective desired positioned when no external force is applied.

The top end 38 of the housing 28 includes a step 60. A cross-sectional area of the first opening 32 is decreased from a first value 62 to a second value 64 along the step 60 and in a direction that extends away from the internal cavity 30. For example, the portion of the first opening 32 where the cross-sectional area is equal to the first value 62 may be sized to receive a four by three inch rectangular tube, conduit, or pipe, while the portion of the first opening 32 where the cross-sectional area is equal to the second value 64 may be sized to receive a three by two inch rectangular tube, conduit, or pipe. In the event the larger-sized connection (e.g., the portion of the top end 38 where the cross-sectional area of the first opening 32 is equal to the second value 64) is required for connecting the housing 28 to the downspout 18, the smaller-sized connection (e.g., the portion of the top end 38 where the cross-sectional area of the first opening 32 is equal to the first value 62) may be cut off from the remainder of the housing 28. For example, the portion of the top end 38 that includes the smaller-sized connection may be cut off from the remainder of the housing 28 by cutting the housing 28 along dashed line 65.

The bottom end 40 of the housing 28 may be sized for connecting to a circular tube, conduit, or pipe. The bottom end 40 of the housing 28 may include clips, snaps, or tabs 66 to connect to a corrugated tube, conduit, or pipe. In the event the bottom end 40 is to be connected to a non-corrugated tube, conduit, or pipe, a portion of the bottom end 40 that includes the clips, snaps, or tabs 66 may be cut off from the remainder of the housing 28. For example, the portion of the bottom end 40 that includes the clips, snaps, or tabs 66 may be cut off from the remainder of the housing 28 by cutting the housing 28 along dashed line 68.

Referring now to FIGS. 3 and 6-7, the filter plate 44 is illustrated in further detail. The filter plate 44 includes a removable central portion 70 that provides access to the lower chamber 50 from the upper chamber 48 when removed. The removeable central portion 70 may be removed so that a hose, jet, heat cable, etc. may be placed into the drainage conduit 20 that is positioned below the bottom end 40 of the housing 28. A hose or jet may be used to clean out the drainage conduit 20. A heat cable may be used to prevent water from freezing within the drainage conduit 20, particularly during the winter months, which could cause damage to the conduit.

The removable central portion 70 of the filter plate 44 is configured to lock and unlock to and from a remainder 72 of the filter plate 44 via rotation relative the remainder 72 of the filter plate 44. The remainder 72 of the filter plate 44 may be referred to as the main portion of the filter plate 44. The removable central portion 70 of the filter plate 44 includes a first set of tabs 74. The remainder 72 of the filter plate includes a second set of tabs 76. The first set of tabs 74 are configured to align with the second tabs 76 to lock the removable central portion 70 of the filter plate 44 to the remainder 72 of the filter plate 44. The remainder 72 of the filter plate 44 defines slots 78. The first set of tabs 74 are configured to align with the slots 78 to unlock the removable central portion 70 of the filter plate 44 from the remainder 72 of the filter plate. The filter plate 44 may include ribs 80 that extending upward from an upper surface 82 of the filter plate 44. The ribs 80 are configured to separate debris from the upper surface 82 of the filter plate 44 to facilitate flow of fluid or water through the filter plate 44. More specifically, the ribs 80 are configured to lift the debris off of the upper surface 82 of the filter plate 44 so the openings 84 defined by the grating of the filter plate 44 are separated from the debris so that the fluid or water may flow through the openings 84.
